Still Need Some Help Narrowing Down Your Options? Here's Some Additional Information to Consider:
The Comfort Scale
Firm Mattresses

If you're considering a firm mattress, a Sleep Sync 12-inch mattress could be a good choice for you. These mattresses feature an indentation load deflection rating of 34-36 pounds and are suitable for those who usually sleep on their back. Providing improved circulation, they promote deeper sleep. They allow for even weight distribution, adequately supporting your joints and other sensitive areas. However, these mattresses can put painful tension on specific pressure points, including the shoulders and hips. In addition, they may be uncomfortable if you're not accustomed to sleeping on hard surfaces, so it can take a couple of days to get used to them.

Plush Mattresses

Are you searching for a plush mattress? A Sleep Sync 12-inch mattress could be a good choice for you. These mattresses have a 19-21 pound indentation load deflection rating and are ideal for those who sleep on their back, sides, or stomach. With added support, they are great for people who experience back problems or joint pain. These contouring support mattresses adjust to your body shape for optimal comfort. However, these mattresses can become lumpy or sag with prolonged use, so your body won't be adequately supported while sleeping. Another drawback is that they may be problematic if various sleepers will be using the bed, causing the surface to sag if there is a drastic difference in weight.

How to Choose a Size for Your Sleep Sync 12-Inch Mattress
King-Size Mattresses

Having trouble deciding what size Sleep Sync 12-inch mattress to get? King-size mattresses are ideal for master bedrooms and measure 76" X 80". They are built to spaciously fit couples, providing maximum space for two people. However, they are not great for small spaces, since they can make the area look somewhat cluttered. Moreover, they are large and heavy, making them difficult to move and flip. Now that you know some things about king-size mattresses, if you think you want one, check out this one.

Full-Size Mattresses

Are you looking for a full-size mattress? This comfortable Sleep Sync 12-inch mattress might be the correct choice for you. Full-size mattresses fit well in studio apartments and measure 54" X 75". They are designed to reasonably accommodate couples, with a snug fit between the two sleepers. However, they are short in length, so they might not be a convenient option if you're taller than 6'3". Also, they have a narrower sleeping space, so you will have limited space to move when sharing your bed with another person.

Queen-Size Mattresses

Are you curious about a queen-size mattress? We think this comfortable Sleep Sync 12-inch mattress could be the correct choice for you. These queen-size mattresses measure 60" X 80" and are ideal for master bedrooms. They are designed to comfortably fit couples, providing some extra space for two people. Something to keep in mind is that they are not suitable for spaces with limited room, so if you live in an apartment or small home, you might want to think about getting a smaller bed. In addition, they are smaller than king-size mattresses, so if you like having a wider sleeping area, you should consider upgrading to a larger mattress.
